Disease relevance of GCNT1

 

High impact information on GCNT1

  • Previously, we discovered by cloning cDNAs that the core 2 branching enzyme, termed core 2 beta-1,6-N-acetylglucosaminyltransferase-leukocyte type (C2GnT-L), is highly homologous to the I branching beta-1, 6-N-acetylglucosaminyltransferase (IGnT) (Bierhuizen, M. F. A., Mattei, M.-G., and Fukuda, M. (1993) Genes Dev. 7, 468-478) [3].
  • These cells lack endogenous C2GnT activity but express a recombinant human MUC1 cDNA [2].
  • Increased C2GnT expression also led to masking of the SM-3 peptide epitope, which persisted after the removal of sialic acid, further suggesting greater complexity of the core 2-associated O-glycans on MUC1 [2].
  • Following transfection and constitutive expression of full-length exogenous C2GnT transcript, C2GnT enzyme activities were maintained at high levels even after TPA treatment and down-regulation of cell surface sLex antigen expression by TPA was completely abolished [4].
  • However, the up-regulation of C2GnT was more dramatic than that of FucT-VII [5].
